Without question, Linux was created by brilliant programmers who employed good computer science knowledge.

Let the Linux programmers whose names you know share the books that got them started and the technology references they recommend for today's developers. How many of them have you read?

An in-depth look into how two leading time-series databases stack up against another.

The purpose of this month's article is to bring once more to the public consciousness some work of Sir Roger Penrose, namely "On the Cohomology of Impossible Figures," which appeared in Structural Topology 17 (1961) pp. 11-16 and was reprinted in Leonardo 25, Nos 3/4 (1992) and then as Chapter 4 of The Visual Mind, Michele Emmer, ed., MIT Press, 1993.

By now, you have likely heard words like "bitcoin" and "blockchain," perhaps even "Ethereum," and wondered what they all mean.

Do they refer to something useful, and if so, how would you go about using it?

This article is intended to put meaning behind these words and others, by highlighting one instance of the technology behind the concepts.

Osquery is an open source Operating System monitoring, query, and analytics software. Created by Facebook, it exposes an operating system as a high-performance relational database that can be queried using SQL-based queries.

Osquery is a multi-platform software, can be installed on Linux, Windows, MacOS, and FreeBSD. Osquery allows us to explore the operating system profile, performance, security and many more metrics by using SQL-based queries.

The alt is a command line tool that helps you to switch between different versions of commands in Unix-like systems. It is a simple, free, open source tool written in Rust programming language.
